Pizza Oven Processing of Organohalide Perovskites (POPOP): A Simple, Versatile and Efficient Vapor Deposition Method

Christophe Ballif, Cédric Bucher, Quentin Jean-Marie Armand Guesnay, Kerem Artuk, Deniz Türkay, Christian Michael Wolff, Austin George Kuba

Hybrid vapor deposition is one of the most appealing processes for perovskite photovoltaics fabrication, thanks to its versatile nature. By using sequentially different vapor deposition processes tailored to the inorganic and organic perovskite precursors' ...

High Efficiency p-i-n a-Si:H Solar Cells with Low Boron Cross-Contamination Prepared in a Large Area Single-Chamber PECVD Reactor

Stefano Benagli, Christoph Hollenstein, Alan Howling, Arvind Shah, Juliette Ballutaud, Cédric Bucher

In this work, a new type of short water vapor treatment of the interface between the p- and i-layer is presented. This novel treatment is performed under vacuum below 1 mbar for 5 min and considerably reduces the i-layer boron contamination in amorphous si ...

Role of i layer deposition parameters on the V0c and FF of an a-Si:H solar cell deposited by PECVD at 27.13 MHz

Stefano Benagli, Arvind Shah, Juliette Ballutaud, Cédric Bucher

A study of the i-layer porosity as a function of the deposition parameters by PECVD technique, is presented here. It is demonstrated in particular, that for a fixed deposition rate of 2 Å/s, increasing the plasma power tends to increase the layer density, ...
